Description
本發明是關於一種觸控感測技術，特別是關於一種觸控感測裝置及其上的濾除誤觸的觸控方法。The invention relates to a touch sensing technology, in particular to a touch sensing device and a touch method for filtering out false touches thereon.
為了提升使用上的便利性，越來越多電子裝置使用觸控螢幕（touch screen）作為操作介面，以讓使用者直接在觸控螢幕上點選畫面來進行操作。因為觸控螢幕能直接提供視覺回饋，所以多半能讓使用者在操作時感到更為便利。觸控螢幕主要由提供顯示功能之顯示器以及提供觸控功能之觸控感測裝置所組成。在輸入操作上，使用者大都是利用手指或觸控筆與觸控螢幕之間所產生的接觸或感應行為來進行操作，以使電子裝置可利用觸碰點的座標變化或觸碰點數量增加或減少，來定義使用者的觸控手勢(gesture)，並進一步依據觸控手勢來執行對應的操作功能。In order to improve the convenience in use, more and more electronic devices use a touch screen as an operation interface, so that users can directly click on the screen to perform operations. Because the touch screen can directly provide visual feedback, it is likely to make the user feel more convenient during operation. The touch screen is mainly composed of a display providing a display function and a touch sensing device providing a touch function. In terms of input operations, users mostly use the contact or sensing behavior generated between the finger or stylus and the touch screen to operate, so that the electronic device can use the coordinate changes of the touch points or increase the number of touch points. Or reduce it to define the user's touch gesture, and further perform the corresponding operation function according to the touch gesture.
使用者在使用觸控螢幕操作電子裝置時，手掌會因書寫習慣或手持電子裝置而觸壓或接近觸控螢幕，以致電子裝置的系統將手掌的位置誤報，造成書寫上的錯誤。此外，當使用者手握於面板邊緣時，一部分的手掌會觸壓於面板的邊緣區，而另一部分的手掌會觸壓於面板的非邊緣區，以致使電子裝置的系統誤認為手指觸控，並且於手掌所造成的觸碰點由邊緣區移至非邊緣區或由非邊緣區移至邊緣區時產生誤動作。When a user uses the touch screen to operate an electronic device, the palm of the hand may touch or touch the touch screen due to writing habits or holding the electronic device, so that the system of the electronic device will misreport the position of the palm, causing a writing error. In addition, when a user holds a hand on the edge of the panel, part of the palm may touch the edge area of the panel, and the other part of the palm may touch the non-edge area of the panel, so that the electronic device system mistakes the finger for touch. , And when the touch point caused by the palm is moved from the edge region to the non-edge region or from the non-edge region to the edge region, a malfunction occurs.
為了避免因部分手掌誤觸動作，又不影響觸控螢幕的使用行為，必須消除手掌觸碰所產生的誤觸動作。因此，如何有效地避免因非所欲之觸控元件（如，手掌）觸碰所造成的誤判及誤動作乃為業界不斷致力研發的方向之一。In order to avoid accidental touch of some palms without affecting the use behavior of the touch screen, it is necessary to eliminate the false touch caused by touching the palm.

When the total number is less than or equal to the first number, it is determined that the touch action of the touch point is a normal touch action; when the total number is greater than or equal to the second number, it is determined that the touch action of the touch point is an invalid touch action.

Here, n and m are positive integers. Furthermore, n may be equal to m or not. The first electrode lines X1 to Xn and the second electrode lines Y1 to Ym are electrically connected to the sensing controller 12.
從頂視視角來看，第一電極線X1~Xn與第二電極線Y1~ Ym相互交錯，並且界定以一矩陣配置之複數偵測點P(1,1)~P(n,m)，如第2圖所示。此些偵測點P(1,1)~P(n,m)形成一感測區16。.From a top perspective, the first electrode lines X1 ~ Xn and the second electrode lines Y1 ~ Ym intersect each other, and define a plurality of detection points P (1,1) ~ P (n, m) arranged in a matrix, As shown in Figure 2. These detection points P (1,1) ~ P (n, m) form a sensing area 16. .
在一些實施例中，交疊後之第一電極線X1~Xn與第二電極線Y1~Ym的頂視圖呈菱形蜂巢狀、網格狀或柵狀。在一些實施例中，第一電極線X1~Xn以及第二電極線Y1~Ym可以位於不同平面（如第1圖所示），即分別位於多個感測層上。其中，多個感測層之間可以但不限於夾置有絕緣層（圖中未示）。在另一些實施例中，第一電極線X1~Xn與第二電極線Y1~Ym可以位於同一平面（圖中未示），也就是僅位於單一感測層上。在一些實施例中，第一電極線X1~Xn為發射電極線，並且第二電極線Y1~Ym為接收電極線。在另一些實施例中，第一電極線X1~Xn為接收電極線，並且第二電極線Y1~Ym為發射電極線。在一些實施例中，感測層可為圖案化導電薄膜，例如：但不限於氧化銦（ITO）錫薄膜。In some embodiments, the top views of the first electrode lines X1 to Xn and the second electrode lines Y1 to Ym after being overlapped are in a diamond-shaped honeycomb shape, a grid shape, or a grid shape. In some embodiments, the first electrode lines X1 to Xn and the second electrode lines Y1 to Ym may be located on different planes (as shown in FIG. 1), that is, respectively located on a plurality of sensing layers. Among them, an insulating layer (not shown) may be interposed between the plurality of sensing layers, but is not limited thereto. In other embodiments, the first electrode lines X1 to Xn and the second electrode lines Y1 to Ym may be located on the same plane (not shown in the figure), that is, only on a single sensing layer. In some embodiments, the first electrode lines X1 to Xn are transmitting electrode lines, and the second electrode lines Y1 to Ym are receiving electrode lines. In other embodiments, the first electrode lines X1 to Xn are receiving electrode lines, and the second electrode lines Y1 to Ym are transmitting electrode lines. In some embodiments, the sensing layer may be a patterned conductive film, such as, but not limited to, an indium oxide (ITO) tin film.
其中，感測區16的周邊既定範圍被定義為一邊緣區域Ae（即，二虛框之間的區域）。舉例來說，觸控感測裝置預設有感測區16的周邊既定範圍為邊緣區域Ae的設定在觸控感測裝置的儲存單元18中。在一些實施例中，此儲存單元18可設置在感測控制器12的外部，且電性連接感測控制器12，如第1圖所示。在另一些實施例中，此儲存單元18可內建在感測控制器12內（圖式未示）。The predetermined range around the sensing area 16 is defined as an edge area Ae (that is, an area between two imaginary frames). For example, the touch sensing device presets a predetermined range of the periphery of the sensing area 16 to be the edge area Ae, which is set in the storage unit 18 of the touch sensing device. In some embodiments, the storage unit 18 may be disposed outside the sensing controller 12 and electrically connected to the sensing controller 12, as shown in FIG. 1. In other embodiments, the storage unit 18 may be built in the sensing controller 12 (not shown).
在一些實施例中，邊緣區域Ae為第一電極線X1~Xn中鄰近於觸控感測裝置（感測區16）的第一側的多條第一電極線與鄰近於觸控感測裝置（感測區16）的第二側的多條第一電極線以及第二電極線Y1~Ym中鄰近於觸控感測裝置（感測區16）的第三側的多條第二電極線與鄰近於觸控感測裝置（感測區16）的第四側的多條第二電極線所構成的感測區。以周邊既定範圍為感測區16周邊三條電極線為例，邊緣區域Ae為第一電極線X1、X2、X3、Xn-2、Xn-1、Xn與第二電極線Y1、Y2、Y3、Ym-2、Ym-1、Ym所構成的感測區。In some embodiments, the edge area Ae is a plurality of first electrode lines adjacent to the first side of the touch sensing device (sensing area 16) in the first electrode lines X1 to Xn and adjacent to the touch sensing device.

在一些實施例中，訊號感測器14可以採用透明或半透明的設計，因此當顯示器20顯示資訊內容時，使用者能透過訊號感測器14而看到顯示器20所顯示的內容。換句話說，顯示器20發出的光線可以穿過訊號感測器14而到達使用者的眼睛。在另一些實施例中，訊號感測器14亦可以不採用透明或半透明的設計，例如：電子畫板或手寫板等不具顯示器20的觸控裝置中的訊號感測器14。In some embodiments, the signal sensor 14 may adopt a transparent or translucent design, so when the display 20 displays information content, the user can see the content displayed on the display 20 through the signal sensor 14. In other words, the light emitted by the display 20 can pass through the signal sensor 14 and reach the eyes of the user. In other embodiments, the signal sensor 14 may not adopt a transparent or translucent design, for example, the signal sensor 14 in a touch device without a display 20 such as an electronic drawing board or a tablet.
當使用者觸碰觸控設備時，觸控感測裝置透過感測區16偵測觸碰事件（觸碰動作），並且由處理單元30基於觸碰事件所對應的位置資訊於做進一步處理。此進一步處理的內容視觸碰事件發生的位置對應顯示器20顯示位置之應用程式而定，例如：但不限於處理單元30響應觸碰事件而啟動某一應用程式、或在觸碰事件發生的位置顯示筆觸等等。在一些實施例中，處理單元30可以是內部的處理器，或者是設置在外部主機中的處理器。When the user touches the touch device, the touch sensing device detects a touch event (touch motion) through the sensing area 16, and the processing unit 30 performs further processing based on the position information corresponding to the touch event. The content of this further processing depends on the application where the touch event occurred corresponds to the display position of the display 20, such as, but not limited to, the processing unit 30 starts an application in response to the touch event, or where the touch event occurs Show strokes and more. In some embodiments, the processing unit 30 may be an internal processor or a processor provided in an external host.
於此，感測控制器12可以採用自電容（self-capacitance）觸控技術或互電容（mutual capacitance）觸控技術藉由訊號感測器14偵測使用者之觸碰動作。感測控制器12除了正常觸控動作的偵測外，另會進行非所欲之觸控元件（如，手掌或部分手掌）觸碰的判斷，以排除非所欲之觸控元件觸碰所造成的誤動作。Here, the sensing controller 12 may use a self-capacitance touch technology or a mutual capacitance touch technology to detect the user's touch motion through the signal sensor 14. In addition to the detection of normal touch actions, the sensing controller 12 also judges whether an undesired touch element (such as a palm or a part of the palm) is touched to exclude an undesired touch element from touching the object. Caused by malfunction.
第3圖為根據本發明一實施例之濾除誤觸的觸控方法的流程圖。FIG. 3 is a flowchart of a touch method for filtering out false touches according to an embodiment of the present invention.
搭配參照第3圖，在使用上，感測控制器12會反覆執行多個掃描週期。在每個掃描週期，感測控制器12進行電極線的掃描（即，偵測感測區16）以得到發生在感測區16上的至少一觸碰點T1、T2（如第4及5圖所示）（步驟S41）。參照第4及5圖，各觸碰點T1（或T2）由多個偵測點P(2,i)、P(2,i+1)、P(3,i)、P(3,i+1)（或P(1,k+2)~ P(1,k+5)、P(2,k+1)~P(2,k+6)、P(3,k)~P(3,k+3)）所構成。其中，i為1至(m-1)之間的正整數。k為1至(m-6)之間的正整數。With reference to FIG. 3, in use, the sensing controller 12 repeatedly executes multiple scanning cycles. In each scanning cycle, the sensing controller 12 scans the electrode lines (ie, detects the sensing area 16) to obtain at least one touch point T1, T2 (such as the 4th and 5th) occurring on the sensing area 16. (Shown in the figure) (step S41). Referring to Figures 4 and 5, each touch point T1 (or T2) consists of multiple detection points P (2, i), P (2, i + 1), P (3, i), and P (3, i +1) (or P (1, k + 2) ~ P (1, k + 5), P (2, k + 1) ~ P (2, k + 6), P (3, k) ~ P ( 3, k + 3)). Where i is a positive integer between 1 and (m-1). k is a positive integer between 1 and (m-6).
然後，感測控制器12進行每一個偵測到的觸碰點T1（或T2）的觸碰動作的屬性判定（即，其為正常觸碰動作、無效觸碰動作或未知觸碰動作）。其中，觸碰點T1（或T2）的觸碰動作是指引發訊號感測器14生成觸碰點的觸碰動作。正常觸碰動作是指由適當的觸控元件（如，手指、觸控畫筆、觸控筆等）所造成的觸碰動作。無效觸碰動作是指由非所欲之觸控元件（如，手掌或部分手掌等）所造成的觸碰動作。未知觸碰動作是指由未知的觸控元件所造成的觸碰動作。Then, the sensing controller 12 determines the attribute of the touch action of each detected touch point T1 (or T2) (that is, it is a normal touch action, an invalid touch action, or an unknown touch action). The touch action of the touch point T1 (or T2) refers to a touch action that causes the signal sensor 14 to generate a touch point. A normal touch action refers to a touch action caused by an appropriate touch element (eg, a finger, a touch pen, a stylus, etc.). An invalid touch action refers to a touch action caused by an unintended touch element (for example, a palm or a part of a palm, etc.). The unknown touch action refers to a touch action caused by an unknown touch element.
為了清楚說明，以下以一個觸碰點T1（或T2）為例進一步說明屬性判定的方法。在觸碰點T1（或T2）的觸碰動作的屬性判定上，感測控制器12會根據第一數量與第二數量確認觸碰點T1（或T2）的偵測點的總數（步驟S43）。其中，第二數量大於第一數量。For the sake of clarity, a touch point T1 (or T2) is taken as an example to further explain the method of attribute determination. In determining the attribute of the touch action of the touch point T1 (or T2), the sensing controller 12 confirms the total number of detection points of the touch point T1 (or T2) according to the first number and the second number (step S43) ). The second number is greater than the first number.
當感測控制器12確認到此觸碰點T1（或T2）的偵測點的總數小於或等於第一數量時，感測控制器12判定此觸碰點T1（或T2）的觸控動作為正常觸控動作（步驟S45）。When the sensing controller 12 confirms that the total number of detection points of the touch point T1 (or T2) is less than or equal to the first number, the sensing controller 12 determines a touch action of the touch point T1 (or T2). It is a normal touch operation (step S45).
當感測控制器12確認到此觸碰點T1（或T2）的偵測點的總數大於或等於第二數量時，感測控制器12判定觸碰點的觸控動作為無效觸控動作（步驟S47）。When the sensing controller 12 confirms that the total number of detected points of the touch point T1 (or T2) is greater than or equal to the second number, the sensing controller 12 determines that the touch action of the touch point is an invalid touch action ( Step S47).
當感測控制器12確認到此觸碰點T1（或T2）的偵測點的總數大於第一數量且小於第二數量（即，落在第一數量與第二數量之間）時，感測控制器12進一步確認此觸碰點T1（或T2）是否屬於邊緣區域Ae（步驟S49）。When the sensing controller 12 confirms that the total number of detection points of the touch point T1 (or T2) is greater than the first number and less than the second number (that is, falls between the first number and the second number), The measurement controller 12 further confirms whether the touch point T1 (or T2) belongs to the edge area Ae (step S49).
在一些實施例中，儲存單元18可預設儲存一數量條件，而感測控制器12可根據一數量條件確認觸碰點T1（或T2）中位於邊緣區域Ae的偵測點的數量，以判定此觸碰點T1（或T2）是否屬於邊緣區域Ae。In some embodiments, the storage unit 18 may preset a quantity condition, and the sensing controller 12 may confirm the quantity of the detection points located in the edge area Ae among the touch points T1 (or T2) according to the quantity condition, and It is determined whether the touch point T1 (or T2) belongs to the edge area Ae.
在一些實施例中，此數量條件可為大於或等於一既定數量（如，1、2或更多等）。換言之，感測控制器12確認觸碰點T1（或T2）中位於邊緣區域Ae的偵測點的數量是否大於或等於此數量閾值。當確認到觸碰點T1（或T2）中位於邊緣區域Ae的偵測點的數量大於或等於此數量閾值時，感測控制器12判定此觸碰點T1（或T2）屬於邊緣區域Ae。當確認到觸碰點T1（或T2）中位於邊緣區域Ae的偵測點的數量小於此數量閾值時，感測控制器12判定此觸碰點T1（或T2）不屬於邊緣區域Ae。舉例來說，以數量條件為大於或等於1為例，當感測控制器12確認到觸碰點T1（或T2）中有任一偵測點位於邊緣區域Ae時，感測控制器12判定此觸碰點T1（或T2）屬於邊緣區域Ae；反之，則判定此觸碰點T1（或T2）不屬於邊緣區域Ae。在另一些實施例中，此數量條件亦可為大於或等於既定比例。換言之，感測控制器12確認觸碰點T1（或T2）中位於邊緣區域Ae的偵測點的數量是否大於或等於觸碰點T1（或T2）的偵測點總量的既定比例。舉例來說，假設觸碰點T1（或T2）的偵測點的總量為3而既定比例30%，感測控制器12確認觸碰點T1（或T2）中位於邊緣區域Ae的偵測點的數量是否大於或等於0.9，且於大於或等於0.9時判定此觸碰點T1（或T2）屬於邊緣區域Ae。In some embodiments, this quantity condition may be greater than or equal to a predetermined quantity (eg, 1, 2 or more, etc.). In other words, the sensing controller 12 confirms whether the number of detection points in the touch point T1 (or T2) located in the edge area Ae is greater than or equal to this number threshold. When it is confirmed that the number of detection points in the touch point T1 (or T2) located in the edge area Ae is greater than or equal to the number threshold, the sensing controller 12 determines that the touch point T1 (or T2) belongs to the edge area Ae. When it is confirmed that the number of detection points in the touch point T1 (or T2) located in the edge area Ae is less than this number threshold, the sensing controller 12 determines that the touch point T1 (or T2) does not belong to the edge area Ae. For example, if the quantity condition is greater than or equal to 1, for example, when the sensing controller 12 confirms that any of the detection points in the touch point T1 (or T2) is located in the edge area Ae, the sensing controller 12 determines The touch point T1 (or T2) belongs to the edge area Ae; otherwise, it is determined that the touch point T1 (or T2) does not belong to the edge area Ae. In other embodiments, the quantity condition may be greater than or equal to a predetermined ratio. In other words, the sensing controller 12 confirms whether the number of detection points in the touch point T1 (or T2) located in the edge area Ae is greater than or equal to a predetermined ratio of the total number of detection points in the touch point T1 (or T2). For example, assuming that the total number of detection points of the touch point T1 (or T2) is 3 and the predetermined ratio is 30%, the sensing controller 12 confirms the detection of the touch point T1 (or T2) in the edge area Ae. Whether the number of points is greater than or equal to 0.9, and when it is greater than or equal to 0.9, it is determined that the touch point T1 (or T2) belongs to the edge area Ae.
當感測控制器12確認到觸碰點T1（或T2）不屬於邊緣區域Ae時，感測控制器12判定觸碰點的觸控動作為無效觸控動作（步驟S47）。When the sensing controller 12 determines that the touch point T1 (or T2) does not belong to the edge area Ae, the sensing controller 12 determines that the touch action of the touch point is an invalid touch action (step S47).
當感測控制器12確認到觸碰點T1（或T2）屬於邊緣區域Ae時，感測控制器12判定觸碰點T1（或T2）的觸控動作為未知觸控動作（步驟S47）。When the sensing controller 12 confirms that the touch point T1 (or T2) belongs to the edge area Ae, the sensing controller 12 determines that the touch action of the touch point T1 (or T2) is an unknown touch action (step S47).
在一些實施例中，當觸碰點T1（或T2）的觸控動作判定為未知觸控動作時，感測控制器12會確認前一掃描週期的判定記錄（步驟S53）。In some embodiments, when the touch action at the touch point T1 (or T2) is determined as an unknown touch action, the sensing controller 12 confirms the determination record of the previous scanning cycle (step S53).
當感測控制器12確認到此觸碰點前一掃描週期的判定記錄為無觸碰（即，前一掃描週期未偵測到相同位置的觸碰點或當前掃描週期為第一個掃描週期）時，感測控制器12將此觸碰點T1（或T2）的觸控動作從判定為未知觸控動作變更為無效觸控動作（步驟S55），也就是將此觸碰點T1（或T2）於當前掃描週期的觸控動作的判定結果強制判定為無效觸控動作。When the sensing controller 12 confirms that the touch point is judged as being touchless in the previous scan cycle (ie, no touch point at the same position was detected in the previous scan cycle or the current scan cycle is the first scan cycle) ), The sensing controller 12 changes the touch action of the touch point T1 (or T2) from being determined as an unknown touch action to an invalid touch action (step S55), that is, the touch point T1 (or T2) The determination result of the touch operation in the current scanning cycle is forcibly determined as an invalid touch operation.
當感測控制器12確認到此觸碰點前一掃描週期的判定記錄為正常觸控動作時，感測控制器12將此觸碰點T1（或T2）的觸控動作從判定為未知觸控動作變更為正常觸控動作（步驟S56），也就是將此觸碰點T1（或T2）於當前掃描週期的觸控動作的判定結果強制判定為正常觸控動作。When the sensing controller 12 confirms that the judgment of the previous scanning cycle of the touch point is recorded as a normal touch action, the sensing controller 12 changes the touch action of the touch point T1 (or T2) from being determined as an unknown touch. The control action is changed to a normal touch action (step S56), that is, the determination result of the touch action of the touch point T1 (or T2) in the current scanning cycle is forcibly determined as a normal touch action.
當感測控制器12確認到此觸碰點前一掃描週期的判定記錄為無效觸控動作或未知觸控動作時，感測控制器12則維持原判定結果，即，判定此觸碰點T1（或T2）於當前掃描週期的觸控動作為未知觸控動作（步驟S57）。When the sensing controller 12 confirms that the judgment of the previous scanning cycle of the touch point is recorded as an invalid touch action or an unknown touch action, the sensing controller 12 maintains the original determination result, that is, determines the touch point T1 (Or T2) The touch action in the current scanning cycle is an unknown touch action (step S57).
在一些實施例中，於屬性判定後，感測控制器12可記錄當前週期的各觸碰點的觸碰動作的判定結果在儲存單元18中（步驟S59）。In some embodiments, after the attribute is determined, the sensing controller 12 may record the determination result of the touch action of each touch point in the current cycle in the storage unit 18 (step S59).
在一些實施例中，感測控制器12可透過不同的標記來記錄各觸碰點的觸碰動作的判定結果。舉例來說，第一標記代表正常觸控動作、第二標記代表無效觸控動作，而第三標記代表未知觸控動作。當感測控制器12判定第一觸碰點的觸控動作為正常觸控動作時，感測控制器12則在當前掃描週期的判定記錄中對應第一觸碰點的代碼或位置資訊標記第一標記。當感測控制器12判定第二觸碰點的觸控動作為無效觸控動作時，感測控制器12則在當前掃描週期的判定記錄中對應第二觸碰點的代碼或位置資訊標記第二標記。當感測控制器12判定第三觸碰點的觸控動作為未知觸控動作時，感測控制器12則在當前掃描週期的判定記錄中對應第三觸碰點的代碼或位置資訊標記第三標記。In some embodiments, the sensing controller 12 can record the determination result of the touch action of each touch point through different marks. For example, the first mark represents a normal touch action, the second mark represents an invalid touch action, and the third mark represents an unknown touch action. When the sensing controller 12 determines that the touch action of the first touch point is a normal touch action, the sensing controller 12 marks the code or position information corresponding to the first touch point in the judgment record of the current scanning cycle. One mark. When the sensing controller 12 determines that the touch action of the second touch point is an invalid touch action, the sensing controller 12 marks the code or position information corresponding to the second touch point in the judgment record of the current scanning cycle. Two marks. When the sensing controller 12 determines that the touch action of the third touch point is an unknown touch action, the sensing controller 12 marks the code or position information corresponding to the third touch point in the judgment record of the current scanning cycle. Three marks.
在一些實施例中，參照第6圖，當觸碰點T1（或T2）的觸控動作判定為手指觸控動作時，感測控制器12會計算此觸碰點T1（或T2）的觸碰動作連續判定為正常觸控動作的一連續次數（步驟S61），並確認連續次數是否達到一次數閾值（以下稱第一閾值）（步驟S63）。In some embodiments, referring to FIG. 6, when the touch action of the touch point T1 (or T2) is determined as a finger touch action, the sensing controller 12 calculates the touch of the touch point T1 (or T2). The touch motion is continuously determined as a continuous number of normal touch motions (step S61), and it is confirmed whether the continuous number of times has reached a threshold (hereinafter referred to as a first threshold) (step S63).
當連續次數達到第一閾值時，感測控制器12會進行此觸碰點T1（或T2）的送點，即，輸出此觸碰點T1（或T2）的位置資訊（步驟S65）。當連續次數未達到第一閾值時，感測控制器12會不進行此觸碰點T1（或T2）的送點，即，不輸出此觸碰點T1（或T2）的位置資訊（步驟S67）。When the number of consecutive times reaches the first threshold, the sensing controller 12 sends the touch point T1 (or T2), that is, outputs the position information of the touch point T1 (or T2) (step S65). When the number of consecutive times does not reach the first threshold, the sensing controller 12 does not send the touch point T1 (or T2), that is, does not output the position information of the touch point T1 (or T2) (step S67). ).
換句話說，當同一觸碰點T1（或T2）在連續次數閾值的掃描週期都被偵測到且被判定為正常觸控動作時，感測控制器12才回報此觸碰點T1（或T2）的位置資訊。In other words, when the same touch point T1 (or T2) is detected in the consecutive number of scanning cycles and determined to be a normal touch action, the sensing controller 12 reports the touch point T1 (or T2).
在一些實施例中，感測控制器12可以每次判定為正常觸控動作時進行累計的方式來計算連續次數，並且在下一掃描週期未偵測到同一觸碰點T1（或T2）或同一觸碰點T1（或T2）未判定為正常觸控動作時重置此觸碰點T1（或T2）累計的連續次數。In some embodiments, the sensing controller 12 may calculate the number of consecutive times in a cumulative manner each time it is determined to be a normal touch action, and the same touch point T1 (or T2) or the same is not detected in the next scanning cycle. When the touch point T1 (or T2) is not determined as a normal touch action, the accumulated consecutive times of the touch point T1 (or T2) are reset.
在另一些實施例中，感測控制器12可透過在判定為正常觸控動作時查詢先前掃描週期的判定記錄，來計算同一觸碰點T1（或T2）連續判定為正常觸控動作的一連續次數。In other embodiments, the sensing controller 12 may query a determination record of a previous scanning cycle when it is determined to be a normal touch action, to calculate a continuous touch of the same touch point T1 (or T2) as one of the normal touch actions. Number of consecutive times.
在一些實施例中，當感測控制器12偵測到觸碰點T1（或T2）但觸碰點T1（或T2）的判定結果為無效觸控動作或未知觸控動作時，感測控制器12均不輸出觸碰點T1（或T2）的位置資訊。In some embodiments, when the sensing controller 12 detects the touch point T1 (or T2) but the determination result of the touch point T1 (or T2) is an invalid touch action or an unknown touch action, the sensing control The transmitter 12 does not output the position information of the touch point T1 (or T2).
在一些實施例中，於觸碰點T1（或T2）開始為報點狀態（即，感測控制器12輸出此觸碰點T1（或T2）的位置資訊）之後，於後續的掃描週期中感測控制器12判定同一觸碰點T1（或T2）的觸控動作為無效觸控動作或未知觸控動作或者感測控制器12未偵測到此觸碰點T1（或T2）（即，未判定為正常觸控動作）時，感測控制器12會查詢先前掃描週期的判定記錄，以確認此觸碰點T1（或T2）於開始為報點狀態後連續幾次未再判定為正常觸控動作。並且，於未再判定為正常觸控動作的連續次數達到另一次數閾值（以下稱第二閾值）時，感測控制器12才停止輸出此觸碰點T1（或T2）的位置資訊。換言之，於開始輸出觸碰點T1（或T2）的位置資訊之後，感測控制器12要連續數個掃描週期未再將觸碰點T1（或T2）的觸控動作判定為正常觸控動作（如，未偵測到此觸碰點T1（或T2）或判定為無效觸控動作或未知觸控動作）時，感測控制器12才停止輸出此觸碰點T1（或T2）的位置資訊。In some embodiments, after the touch point T1 (or T2) starts to report the point state (that is, the sensing controller 12 outputs position information of the touch point T1 (or T2)), in a subsequent scanning cycle The sensing controller 12 determines that the touch action of the same touch point T1 (or T2) is an invalid touch action or an unknown touch action or the sensing controller 12 does not detect this touch point T1 (or T2) (that is, , It is not judged as a normal touch action), the sensing controller 12 will query the judgment record of the previous scanning cycle to confirm that the touch point T1 (or T2) has not been judged as a consecutive number of times Normal touch action. In addition, when it is not determined that the consecutive number of consecutive touch operations reaches another threshold (hereinafter referred to as a second threshold), the sensing controller 12 stops outputting the position information of the touch point T1 (or T2). In other words, after starting to output the position information of the touch point T1 (or T2), the sensing controller 12 does not judge the touch action of the touch point T1 (or T2) as a normal touch action for several consecutive scanning cycles. (For example, when the touch point T1 (or T2) is not detected or determined as an invalid touch action or an unknown touch action), the sensing controller 12 stops outputting the position of the touch point T1 (or T2). Information.
在一些實施例中，第二閾值可為2。換言之，於開始輸出觸碰點T1（或T2）的位置資訊之後，感測控制器12連續二個掃描周期都未再將此觸碰點T1（或T2）的觸控動作判定為正常觸控動作時，感測控制器12則停止輸出觸碰點T1（或T2）的位置資訊。In some embodiments, the second threshold may be two. In other words, after starting to output the position information of the touch point T1 (or T2), the sensing controller 12 does not judge the touch action of this touch point T1 (or T2) as a normal touch for two consecutive scanning cycles. When in motion, the sensing controller 12 stops outputting the position information of the touch point T1 (or T2).
舉例來說，假設觸碰點T1~T3的判定記錄如下表一所示。其中，F為代表正常觸控動作的第一標記、P為代表無效觸控動作的第二標記，而U為代表未知觸控動作的第三標記。For example, suppose the determination records of the touch points T1 to T3 are shown in Table 1 below. Among them, F is a first mark representing a normal touch action, P is a second mark representing an invalid touch action, and U is a third mark representing an unknown touch action.
表一
觸碰點T1在第1到4個掃描週期都未偵測到（無觸碰記錄）。在第5到12個掃描週期，感測控制器12偵測到觸碰點T1。在第6到12個掃描週期，感測控制器12判定觸碰點T1的觸控動作為未知觸控動作並且不輸出觸碰點T1的位置資訊。在第5個掃描週期，感測控制器12原判定觸碰點T1的觸控動作為未知觸控動作，但因第4個掃描週期並未偵測到觸碰點T1，因此判定結果強制為無效觸控動作且不輸出觸碰點T1的位置資訊。The touch point T1 is not detected in the first to fourth scanning cycles (no touch recording). In the 5th to 12th scanning periods, the sensing controller 12 detects the touch point T1. In the 6th to 12th scanning periods, the sensing controller 12 determines that the touch action of the touch point T1 is an unknown touch action and does not output the position information of the touch point T1. In the fifth scan cycle, the sensing controller 12 originally determined that the touch action at the touch point T1 was an unknown touch action, but because the touch point T1 was not detected in the fourth scan cycle, the determination result is forced to be The touch operation is invalid and the position information of the touch point T1 is not output.
在第1到12個掃描週期，感測控制器12偵測到觸碰點T2。其中，在第2個及第3個掃描週期，感測控制器12判定觸碰點T2的觸控動作為正常觸控動作。在第1個及第4個掃描週期，感測控制器12判定觸碰點T2的觸控動作為無效觸控動作；而在第5到12個掃描週期，感測控制器12則判定觸碰點T2的觸控動作為未知觸控動作。假設第一閾值為3，由於觸碰點T2只連續判定為正常觸控動作2次（未達第一閾值），因此感測控制器12在第1到12個掃描週期均不輸出觸碰點T2的位置資訊。In the first to twelfth scanning periods, the sensing controller 12 detects the touch point T2. In the second and third scanning cycles, the sensing controller 12 determines that the touch operation at the touch point T2 is a normal touch operation. In the first and fourth scanning cycles, the sensing controller 12 determines that the touch action at the touch point T2 is an invalid touch action; and in the fifth to twelfth scanning cycles, the sensing controller 12 determines the touch The touch action at point T2 is an unknown touch action. Assume that the first threshold value is 3, and since the touch point T2 is only determined to be a normal touch action twice (below the first threshold value), the sensing controller 12 does not output the touch point in the first to twelfth scanning cycles. T2's location.
在第1到12個掃描週期，感測控制器12偵測到觸碰點T3。其中，在第2到9個掃描週期，感測控制器12判定觸碰點T3的觸控動作為正常觸控動作。於此，第5個掃描週期，感測控制器12原判定觸碰點T3的觸控動作為未知觸控動作，但因觸碰點T3於第4個掃描週期的判定記錄為正常觸控動作，因此感測控制器12將觸碰點T3於第5個掃描週期的判定結果強制為正常觸控動作。同樣地，第6到9個掃描週期，感測控制器12原判定觸碰點T3的觸控動作為未知觸控動作，但因前一個掃描週期的判定記錄為正常觸控動作，因而都被強制判定為正常觸控動作。在第1個及第10到12個掃描週期，感測控制器12判定觸碰點T3的觸控動作為無效觸控動作。假設第一閾值為3且第二閾值為2。由於在第4個掃描週期觸碰點T3連續判定為正常觸控動作3次（達第一閾值），因此感測控制器12在第4個掃描週期開始輸出觸碰點T3的位置資訊。雖然在第10個掃描週期，感測控制器12已判定觸碰點T3的觸控動作為無效觸控動作，但連續次數未達第二閾值，因此感測控制器12維持輸出觸碰點T3的位置資訊。在第11個掃描週期，感測控制器12再次判定觸碰點T3的觸控動作為無效觸控動作（連續2次未再判定為正常觸控動作，即連續次數達第二閾值），因此感測控制器12停止輸出觸碰點T3的位置資訊。換言之，在第1到3個掃描週期及第11至12個掃描週期，感測控制器12不輸出觸碰點T3的位置資訊。而在第4到10個掃描週期，感測控制器12輸出觸碰點T3的位置資訊。In the first to twelfth scanning cycles, the sensing controller 12 detects the touch point T3. In the second to ninth scanning periods, the sensing controller 12 determines that the touch operation at the touch point T3 is a normal touch operation. Here, in the 5th scanning cycle, the sensing controller 12 originally determined that the touch operation of the touch point T3 was an unknown touch motion, but the determination of the touch point T3 in the 4th scanning cycle was recorded as a normal touch motion. Therefore, the sensing controller 12 forces the determination result of the touch point T3 in the fifth scanning cycle to be a normal touch action. Similarly, in the 6th to 9th scanning periods, the sensing controller 12 originally determined that the touch action at the touch point T3 was an unknown touch action, but because the judgment of the previous scan period was recorded as a normal touch action, they were all Forcibly determined as a normal touch action. In the first and tenth to twelfth scanning cycles, the sensing controller 12 determines that the touch operation at the touch point T3 is an invalid touch operation. Assume that the first threshold is 3 and the second threshold is 2. Since the touch point T3 is continuously determined to be a normal touch action three times (up to a first threshold value) in the fourth scanning cycle, the sensing controller 12 starts to output the position information of the touch point T3 in the fourth scanning cycle. Although in the 10th scanning cycle, the sensing controller 12 has determined that the touch action of the touch point T3 is an invalid touch action, but the number of consecutive times does not reach the second threshold, so the sensing controller 12 maintains the output touch point T3 'S location. In the 11th scanning cycle, the sensing controller 12 again determines that the touch action at the touch point T3 is an invalid touch action (not determined as a normal touch action twice in a row, that is, the number of consecutive times reaches the second threshold), The sensing controller 12 stops outputting the position information of the touch point T3. In other words, during the 1st to 3rd scanning periods and the 11th to 12th scanning periods, the sensing controller 12 does not output the position information of the touch point T3. In the 4th to 10th scanning periods, the sensing controller 12 outputs the position information of the touch point T3.
應當可理解的是，各步驟的執行順序並不限於前述描述順序，可依據步驟的執行內容適當地調配執行順序。舉例來說，雖然圖式中是示意最後執行步驟S59，然本發明不限於此，觸碰點的觸碰動作判定確定（步驟S45、S47、S55、S57）後的任意時刻執行，如在步驟S61前進行判定結果的記錄（步驟S59）。It should be understood that the execution order of each step is not limited to the foregoing description order, and the execution order may be appropriately allocated according to the execution content of the steps. For example, although the figure shows the final execution of step S59, the present invention is not limited to this. The touch action of the touch point is determined (steps S45, S47, S55, S57) at any time after the determination, such as in step Recording of the judgment result is performed before S61 (step S59).
在一些實施例中，儲存單元18亦可用以儲存運作所需之程式、參數及數據等（如，實現任一實施例之濾除誤觸的觸控方法的程式、第一數量、第二數量及閾值等）。此儲存單元可由一個或多個記憶體元件實現。各記憶體元件可為唯讀記憶體、隨機存取記憶體、非永久性記憶體、永久性記憶體、靜態記憶體、動態記憶體、快閃記憶體和/或任何存儲數位資訊的設備。In some embodiments, the storage unit 18 may also be used to store programs, parameters, and data required for operation (for example, a program, a first quantity, and a second quantity to implement a touch method for filtering out false touches of any embodiment. And thresholds, etc.). This storage unit may be implemented by one or more memory elements. Each memory element may be a read-only memory, a random access memory, a non-persistent memory, a permanent memory, a static memory, a dynamic memory, a flash memory, and / or any device that stores digital information.

In some embodiments, the computer program product may be a readable recording medium, and the program is stored in the readable recording medium for the computer to load. In some embodiments, the program itself can be a computer program product, and can be transmitted to the touch device through a wired or wireless method.
綜上，根據本發明之觸控感測裝置及濾除誤觸的觸控方法，其得以判斷觸碰事件是否由非所欲之觸控元件（如，手掌或部分手掌）所造成，進而排除因非所欲之觸控元件觸碰所造成的誤動作。In summary, according to the touch sensing device of the present invention and the touch method for filtering out false touches, it is possible to determine whether a touch event is caused by an unintended touch element (such as a palm or a part of the palm), and then rule out Misoperation caused by unintended touch of a touch element.
